??? I don't quite understand what you mean? Why did you quote that specific quote? Are you saying AGTP isn't amazing, or Cave Story isn't amazing? And what does this have to do with Undertale. Cave Story and Undertale are literally nothing alike. So many questions...
Also, Hayden, I'm having some issues and my game is all screwed up now, but I think I know the issue and how to fix it, while keeping the AGTP translation. Good thing I made a backup!
Edit: Yay! I fixed it! My saves work, no more crashing, and I have the AGTP translation now! Thanks man, I have always wanted to do this with Cave Story+.
Now, if only here was a way to do this with the Wii and DSi ware ports...
Second Edit: Well, in my testing, I found out that the Boss time attack and Sanctuary time attack challenges don't work (everything else does, though). At first I thought that this was due to the translation pack, but when I restored from backup, they were still screwed up. I think this issue has existed way before now, I've just not noticed since I almost never go into those modes. So now I'm reinstalling, and I'll fix it tomorrow. I've put way too much time into Cave Story today.
